2023 Battery Electric Vehicle (EV or BEV) Driving and Fuel Statistics

Writ­ten 4/29/23 — Updat­ed 2/21/2024

Purpose

Report­ing on Trip and Fuel Sta­tis­tics for dri­ving a bat­tery elec­tric vehi­cle (BEV). Specif­i­cal­ly the 2023 Ford Mus­tang Mach-E4

Location

North­ern VA

What

Data obtained from In-car Dash, Ford­Pass App, Charg­ing Sta­tions, and Home Charg­er

Duration

As long as I own the vehi­cle. Start Date: Jan­u­ary 21, 2023

Notes

This is pri­mar­i­ly City dri­ving with mod­er­ate traf­fic

ADJ: “Adjust­ed” — Adjust­ed for a par­tic­u­lar trip’s bat­tery capac­i­ty which is gov­erned by fac­tors such as tem­per­a­ture. Every EV has an ide­al bat­tery capac­i­ty. This can be exceed­ed or under­cut, which there­fore affects the rest of met­rics like MPGe and ener­gy effi­cien­cy.

Aver­age Trip Speed: Not aver­age speed dri­ven dur­ing trip, but speed when tak­ing into account miles dri­ven and time dura­tion of trip

MPGe: Based off the EPA con­ver­sion: 33.705kWh elec­tric­i­ty = 1 gal­lon gaso­line

Aver­age Tem­per­a­ture: As report­ed by Weath­er Under­ground His­tor­i­cal Data for Dulles Air­port

What

A per­son­al ultra­son­ic den­tal appli­ance clean­er for night­guards, den­tures, align­ers, retain­ers, and sleep apnea appli­ances. High fre­quen­cy vibra­tion (108Z??? “Z” is not a real fre­quen­cy unit of mea­sure) with auto-shut­off fea­ture, 3 timer set­tings (5, 10, 15 min­utes), and 2 pow­er options (includ­ed 3 AAA or USB A with no charg­ing block).

Dr. B (Lorin Berland, DDS) has pur­port­ed­ly authored over 100 book, arti­cles, and videos on clin­i­cal den­tistry and edu­a­tion.

Verdict

Rec­om­mend­ed: Yes, with reser­va­tions

Pros: Com­pact, well-made, nice half-screw cap, sim­ple

Cons: Zero tech­ni­cal infor­ma­tion, made-up fre­quen­cy num­bers in Ama­zon descrip­tion and absent on offi­cial web­site,

You be the judge in the pic­tures. The “after” pho­tos are notice­ably whiter and show less tar­tar. How­ev­er, it’s not 100% clean. While the clean­er was work­ing, I felt as if it was­n’t as strong as I’d like it to be. The ones in my office sound and look strong when in use. It clear­ly works and pos­si­bly with repeat­ed use it would fur­ther clean my night­guard, but how much of that is just the tablet and how much is the ultra­son­ic prod­uct, itself? I have not done a test for just those Poli­dent retain­er tablets. My biggest prob­lem with the device is the over­all lack of infor­ma­tion. You can look up 108Z if you want on the inter­net, but noth­ing in the fre­quen­cy world has that unit of mea­sure. Is it made up? It’s Hz. Fre­quen­cy is mea­sured in Hz. The prod­uct also did not come with book­let, nor does it offer one any­where in the Ama­zon list­ing, on the offi­cial web­site nor on a den­tal prod­uct dis­trib­u­tor site. That’s a lit­tle shady, in my opin­ion. Then again, it’s also only $30 where­as a com­pa­ra­ble by iSon­ic runs $50, and it clear­ly does work.

Dis­claimer: I am a Den­tal Hygien­ist by trade and am test­ing these on my own with NO com­pen­sa­tion from any­one
